Hi William,
I have submitted quite a few orphan drug designation requests to the FDA. The typical response time has ranged between 60 and 90 days.
I once searched all of the prohan drug information on the FDA website and found no information about the timing for their response to orphan designation requests. So I called the agencyand asked about that. The response I received was that there was not a set review time or even a formal target but that they tried to aim for 60 days as an informal target. In my experience they have responded within 60 to 90 days, as I said.
Best regards,
Kathy

FDA Orphan Drug Designation Holders--
Will you please share how long (initial submission to notification) it took FDA to complete the review of your application?
Thanks.
